Always leave your PC on while you watch the latest Game of Thrones? Someone at Microsoft evidently does. A granted patent outlines a model that uses historical usage data to predict when it might be able to tweak power needs of the processor in the future, and for how long. So, perhaps you leave your machine on overnight, and jump on at 8am every day? It'd know this and make frugal use of resources accordingly. This, of course, could help fill your pockets and maybe cover that upgrade.
